DESCRIPTION
XkbLockModifiers sends a request to the server to lock the real modi-
fiers selected by both affect and values and to unlock the real modi-
fiers selected by affect, but not selected by values. XkbLockModifiers

request was sent, and False otherwise.

mask in the parameter affect. It is a bitwise inclusive OR of the legal
modifier masks:
